To all whom it may concern:

Be it known that I, WILLIAMl-F. GnoENn, a citizen of the United States, and a resident of the city of Cincinnati, in the county of I-Iamilton' and ,State of Ohio, have invented certain new and useful Improve- Lathes, of

which the following is a full, c ear,andwex act description.

An object ofmy inventionis a lathe having a turning tool, a facing tooland auto- 1 matic means for feeding the tools simultaneously.

Another object of my invention is a means for varying the mlative rates of I feed in a lathe of the aforesaid character.

. Another object of my inventionis an improved means for feeding the facing attachtion.

of the lathe bed andthe drive "ment of a lathe.

' These andother objects are attained by the means described in the specification and illustrated in the accompanying drawings, in-whichy Fig. '1 is a perspective-view, looking from the rear, of a latheembodying my inven- Fig. 2 is. sectional view taken upon line 2-2 of Fig. 1. Y

Fig. 3 is a perspective view of apart of the lathe bed, the head and tailstocks and the supports for the facing and turning tools, the view being taken from the front of the machine.

Fig. 4 is a detail front elevation of a part shaft, the housings for the gear for transmitting mo- .tion. thru the drive shaft to the shafts v which drive the facing bar slide and the carriageto theturning tool, parts being broken away to disclose the parts in the rear of them.

vide means for conveying from the drive shaft F, longitudinal movement to the car riage E and simultaneously 'th'erewith a transverse movement of the facing tool support (1, and means for varying the relative a worm wheel 9 which meshes with a worm upon the drive shaft F. S 'lined upon shaft 9 is a eluth g which may be moved by clutch lever 9 (see Fig; 3), so as to fix the worm wheel g upon the shaft 9. Shaft g has fixed upon it a pinion g which is in mesh with the gear 7 wheel g, which is mounted upon, a transverse shaft g, at the inner end of which is secured a pinion g which meshes with the internal teeth upon the gear wheel 9", which is secured upon a gear 9 is keyed to the sleeve of a gear 9 concentric with the gear 9". The gear or pinion 9 engages a bull wheel G which meshes with a rack E which is Original NO. 1,393,115, dated October 11, 1921, Serial R0. 362,227, filed March 1, 1920.

secured upon the carriage E. -The bull wheel G is mounted upon a stud shaft g carried by the lathe bed. The speed of the carriage E may be varied by changing the gear wheels 9 and g.

Transverse reciprocation is imparted to the facing tool support d as follows :,Sup-

port d is mounted in transverse ways a? upon carriage D, and has upon its under side a rack J, the teeth of,which are engaged by a pinion (P, which is mounted upon a longitudinal stud shaft d" which is secured in carriage D. Rotation is impartedto pinion d by a vertical rack (1* which is mounted in ve'rticai ways upon the rear, of carriageD and has vertical reciprocation im-,

parted to it by means of ashoe d which is seated in ways d in guide 02, which is 'mounted adjustably upon a carriage D which reciprocates in longitudinal ways a upon the rear'of the lathe bed A. Guide (Z is mounted upon the carriage D by means (1, whose heads are seated in dovetailed grooves in carriage D. Bolt 03 engages a grooved slot (1 in one end of the guide of, so that the guide may be set at the taine angle desired by means of the bolt and carries at its reanend a gear .the work which is to e faced is of the slot (1". Motion is conveyed to the carriage D by the following mechanism. Shaft g has secured upon it a gear wheel d which meshes with the gear wheel d whichis secured upon the front end of a transverse shaft D, which is mounted in the lathe bed in; journalbearings d, 1 and inion d, which meshes with a rack d" w i'ch is secured to the carriage D' Various relative sizes of. gears d and d" ma be mounted uponshafts g and D where y changes in the relative speeds of reciprocation of the facin tool and the turning tool may be obwithout changing the angle of the guide bar, and by changes both 0 the angle of the angle bar andthe sizes of said gears a great variety of feeds of said tools may be had. y

In operation the slide dis adjusted to and fixed at an angle which will give the cation to the facing tool, in

I roportion to the feed of the turnin tool. l

f the part of reater width, than the part of the work w ich is to be turned, the reci rocation of the facing tool is made greater t an that of the turning tool, The speed of the reciprocation of the facing tool is in direct proportion tothe nclination of the guide d, that is the more the guide is inclined from thehorizontal the faster the speed of the reciprocation of the facing toolkwith the same ratio of size of the gear w eels d and d a The variations of the operations of the I turning tool and the facing tool, which may be obtained 1b the relative feedin of the facing tool an the turning tool to t e work,

by means of their feed regulators, will be apsparent to those skilled in the art, who will appreciate that various turning and facing attachments may be carried on simultaneously byrthe mounting of varigus facin and turning tools upon the respective facing and turnin'g support, as illustrated upon the work H in. Fig. 3.

Having'thus described my invention, what I claim is:
